A Multiple Interval Chebyshev-Gauss-Lobatto Collocation Method for Ordinary Differential Equations

摘要

We introduce a multiple interval Chebyshev-Gauss-Lobatto spectral collocation method for the initial value problems of the nonlinear ordinary differential equations (ODES).This method is easy to implement and possesses the high order accuracy.In addition,it is very stable and suitable for long time calculations.We also obtain the hp-version bound on the numerical error of the multiple interval collocation method under Hi-norm.Numerical experiments confirm the theoretical exDectations.
